At one age, cars with a tome transmission got significantly bigger Gauze milage than models with automatic transmissions. Latest advances in automatic transmissions carry narrowed the hole, on the other hand depending on the specific type of vehivle and the valuation of petrol, guidebook transmissions can much aid you save bankroll on Gauze.
Most sedans and compact cars with manual transmissions bias up to 1 enhanced mile per gallon (mpg) than automatic versions of the equivalent vehicle. For instance, the 2009 Honda Civic Sedan with a book transmission gets an estimated 26 mpg in the conurbation, 34 mpg on the highway and 29 mpg with a combination. With an automatic transmission, the duplicate machine gets approximately 25 mpg in the conurbation, 36 mpg on the highway and 29 mpg with a combination. This funds the notebook Honda Civic gets approximately 1 mpg enhanced than automatics for municipality driving, 2 mpg less on the highway and no digression overall.
The 2009 Hyundai Accent has a akin mpg replica. Models such as the 2009 Ford Heart, Toyota Yaris and Mazda 3 invest in enclosing 1 mpg exceeding overall with a tome transmission. Other models, such as the 2009 Toyota Corolla, bias the corresponding mpg with either type of transmission.
Pickup trucks such as the 2009 Chevy Colorado 2WD (4 cyl.) show no difference in gas mileage by transmission type, while the 2009 Toyota Tacoma (4 cyl.) and Ford Ranger 2WD (6 cyl.) get about 1 mpg more. In contrast, the 2009 Ford Ranger 2WD with a 4 cylinder engine gets about 2 mpg more with a manual transmission.
Time FrameInconsequential wagons, such as the 2009 Subaru Impreza Outback and Toyota Matrix, generally panoply minor or no Gauze resources with a manual transmission. However, the manual 2009 Pontiac Vibe gets up to 2 mpg more than the automatic. Sport utility vehicles (SUVs) with a manual transmission such as the 2009 Subaru Forester, Jeep Compass, Ford Escape and Suzuki Grand Vitara get up to 1 more mpg overall than the automatic version, with the manual Ford Escape getting about 2 mpg more for city driving.
In general, the gap in miles per gallon (mpg) between manual and automatic transmissions is larger for older vehicles than it is for recent models. This is mainly due to increased efficiency in automatic transmissions. For example, the 1990 Honda Civic got an estimated 28 mpg in the city, 33 mpg on the highway and 30 mpg in combination driving with a manual transmission, while the automatic version got about 24 mpg in the city, 30 mpg on the highway and 26 mpg in combination driving. This represents a difference of about 4 mpg compared to no overall difference for the 2009 model.
How much gas money a manual transmission saves depends on how many more mpg it gets than an automatic, and the price of gas. For example, in December 2008, the average nationwide price for one gallon of regular gas was about $1.67, compared to about $4.11 in July 2008. A commuter driving 15 miles each way five days per week, or a total of 150 miles, with an automatic transmission car that gets 20 mpg would need 7.5 gallons of gas. If the same car with a manual transmission gets 21 mpg, the same commuter would need 7.14 gallons of gas. At $1.67 per gallon, the car with a manual transmission would save about 60 cents, or $31.20 over the course of a year. At $4.11 per gallon, the commuter would save about $1.48, or about $79.96 over the course of a year.
With new cars and trucks, there is often a greater difference in gas mileage between makes and models than there is between manual and automatic versions of the same vehicle. For example, the 2009 Toyota Yaris gets an estimated 31 to 32 mpg overall depending on transmission type, while the 2009 Volkswagen Jetta gets an estimated 24 mpg overall with either transmission type. The website Fueleconomy.gov, linked below, gives users the estimated mpg for many types of vehicles, going as far back as 1985. It also allows users to do a side-by-side comparison of two or more vehicles, to see how they compare in gas savings.
